Hi @swirt,

Can I start working on this?

@nidhi27 Thank you for checking. Sorry, I think this is blocked until we get the UX finalized. ✨ UX for design for module admin Active
Several UX people are meeting on this in a couple days, so we might have designs by next week.

HI @swirt,

Ok will start after that. Thanks!

Closing this as the latest design has this rule live cleanly in with rest of the rules.
